# faq
? How many domains does Atos secure?
Atos is the certificate authority for 83 active domains as of October 15, 2026 - 0.00% of every domain DNSniffer can attribute to an issuer.

The number of domains secured by Atos has grown by 2.47% over the last year (+2 domains).
? Which intermediate CAs does Atos sign from?
We have seen 2 intermediates under Atos, the busiest being “Atos TrustedRoot Server CA RSA 2022” with 69 domains. The full list, with per-intermediate counts, is on this page.
? Where does this number come from?
DNSniffer ingests Certificate Transparency logs continuously and records the issuer of the most recent certificate seen for each domain, then snapshots the per-issuer count once a day. It measures how much of the live web a CA currently secures, not how many certificates it has issued over its lifetime.
